MIAMI — Dwyane Wade's game is built on his ability to blow past defenders and soar to the hoop.

On Wednesday, Miami's star guard could hardly walk.

Getting the Heat back into the NBA finals came at a steep price.

Wade, who had to be driven on a cart to and from an interview session, spent the off day before tonight's Game 4 receiving treatment on a bum left knee he injured in a freakish collision with teammate Shaquille O'Neal during the second half of Miami's 98-96 win in Game 3 over the Dallas Mavericks.

"It's very stiff and very sore," said Wade, who scored 42 points. "So the only thing I can continue to do is what I'm ordered to do, and that's a lot of icing and stim (electric stimulation). I'm confident in my training staff that they'll get me as close as I can be to 100 percent.

"So, you know, I'm hoping."
